本发明涉及用于生产含有生物碱的材料的片材的方法。特别地，本发明涉及用于生产用于气溶胶生成制品(诸如香烟或“加热不燃烧”型含生物碱的产品)中的材料的片材的方法。The present invention relates to a method for producing sheets of alkaloid-containing material. In particular, the present invention relates to methods for producing sheets of material for use in aerosol-generating articles such as cigarettes or "heat-not-burn" alkaloid-containing products.
背景技术Background technique
当今，在制造除烟草叶外的烟草产品时，也使用均质化烟草材料。这种均质化烟草材料通常由例如烟草梗或烟草尘等不大适合生产切丝填料的烟草植物部分制造。通常，烟草尘是在制造期间处理烟草叶的过程中作为副产品而产生。Homogenized tobacco material is also used today in the manufacture of tobacco products other than tobacco leaf. Such homogenized tobacco material is typically produced from parts of the tobacco plant that are less suitable for the production of cut filler, such as tobacco stems or tobacco dust. Typically, tobacco dust is produced as a by-product during the handling of tobacco leaves during manufacture.
均质化烟草材料最常使用的形式是再生烟草片材和流延叶。用以形成均质化烟草材料片材的工艺通常包括将烟草尘与粘合剂混合以形成浆料的步骤。接着使用浆料形成烟草幅板，例如通过将粘稠的浆料流延于移动的金属带上以产生所谓的流延叶。或者，可使用具有低黏度和高含水量的浆料在类似造纸的工艺中产生再生烟草。在制备后，可以类似方式将均质化烟草幅材切割成全叶烟草，以生产适于香烟和其它吸烟制品的烟草切丝填料。用于制造这类均质化烟草的工艺例如在欧洲专利EP0565360中公开。The most commonly used forms of homogenized tobacco material are reconstituted tobacco sheet and cast leaf. Processes for forming sheets of homogenized tobacco material typically include the step of mixing tobacco dust with a binder to form a slurry. The slurry is then used to form a tobacco web, for example by casting the viscous slurry onto a moving metal belt to produce a so-called cast lobe. Alternatively, reconstituted tobacco can be produced in a paper-like process using a slurry with low viscosity and high water content. After preparation, the homogenized tobacco web can be cut into whole leaf tobacco in a similar manner to produce tobacco cut filler suitable for cigarettes and other smoking articles. A process for making such homogenized tobacco is disclosed, for example, in European patent EP0565360.
在上述过程中，将浆料流延在诸如移动带的基材上，然后对其进行加热以便获得材料的片材，该材料的片材可被进一步处理以获得用于气溶胶生成制品的组分。其上具有流延片材的移动带在长“干燥器”内部移动，其中温度被控制以逐渐加热和干燥片材。为了干燥流延片材，干燥器通常朝向片材的顶表面喷射热空气流，并朝向钢带的底表面喷射蒸汽以加热钢带的底表面。沉积在带上的浆料以基本上液体形式进入干燥器，在干燥器内部被干燥和加热，并且以基本上固体形式作为连续流延片材离开。In the process described above, the slurry is cast on a substrate such as a moving belt, which is then heated in order to obtain a sheet of material which can be further processed to obtain a composition for use in aerosol-generating articles. point. A moving belt with the cast sheet on it moves inside a long "dryer" where the temperature is controlled to gradually heat and dry the sheet. To dry the cast sheet, the dryer typically sprays a stream of hot air toward the top surface of the sheet and steam toward the bottom surface of the steel strip to heat the bottom surface of the steel strip. The slurry deposited on the belt enters the dryer in substantially liquid form, is dried and heated inside the dryer, and exits as a continuously cast sheet in substantially solid form.
上述干燥过程需要大量能量来加热和干燥片材。该热量的一部分有效地传递到片材并对其进行干燥(蒸发潜热)。当热的干燥空气和蒸汽经由干燥器的排放物排出时，一些附加热量保持在该热的干燥空气和蒸汽中，或者在片材已从加热的移动金属带移除之后，一些附加热量保留在该加热的移动金属带中。The drying process described above requires a large amount of energy to heat and dry the sheet. A portion of this heat is effectively transferred to the sheet and dries it (latent heat of evaporation). Some additional heat remains in the hot drying air and steam as it exits via the dryer discharge or after the sheet has been removed from the heated moving metal belt. The heated moving metal belt.
此外，在该干燥过程期间，存在于片材中的一些香料和生物碱被蒸发的水捕获，然后被蒸气从干燥片材带走。Furthermore, during this drying process, some of the fragrances and alkaloids present in the sheet are captured by the evaporated water and then carried away from the dried sheet by the vapor.
期望增加干燥阶段的效率。因此，需要制备含有生物碱的材料的片材的新方法，该材料的片材优选但不一定用于“加热不燃烧”型的加热的气溶胶生成制品中，该方法适于干燥过程的上述加热特性。It is desirable to increase the efficiency of the drying stage. Accordingly, there is a need for new methods of preparing sheets of alkaloid-containing material, preferably but not necessarily for use in heated aerosol-generating articles of the "heat-not-burn" type, which are suitable for the above-mentioned aspects of the drying process. heating characteristics.

将含有包括生物碱的材料的浆料流延在例如支撑件上。在干燥器中使用加热流体将所得的流延片材干燥，该加热流体与流延片材交换热量。加热流体可加热并干燥片材。在该干燥过程期间，产生排放物。根据本发明，排放物被收集并且从其中回收热量。这样，原本浪费在排放物中的热量例如在生产片材的相同过程中可被重复使用。The slurry containing the alkaloid-containing material is cast, for example, on a support. The resulting cast sheet is dried in a dryer using a heating fluid that exchanges heat with the cast sheet. The heating fluid heats and dries the sheet.

The movable supports form a closed loop to provide uninterrupted transmission in one direction. The movable support may comprise a conveyor belt. The movable support may be substantially flat and may exhibit a structured or unstructured surface. The movable support may have no openings on its surface, or may include orifices preferably sized to be impermeable to slurry deposited thereon. The movable support may comprise a sheet-like movable and bendable belt. The straps may be made of metallic materials, including but not limited to steel, copper, iron alloys and copper alloys, or rubber materials.

They can be purified from crude extracts of these organisms by acid-base extraction. Caffeine, nicotine, theobromine, atropine, tubocurarine are examples of alkaloids.
优选地，含有生物碱的材料包括均质化烟草材料。因此，在这种情况下，生物碱是尼古丁。如本文中所使用，术语“均质化烟草材料”表示通过聚结颗粒烟草形成的材料，其含有生物碱尼古丁。Preferably, the alkaloid-containing material comprises homogenized tobacco material. So, in this case, the alkaloid is nicotine. As used herein, the term "homogenized tobacco material" means a material formed by agglomerating particulate tobacco, which contains the alkaloid nicotine.
均质化烟草材料最常使用的形式是再生烟草片材和流延叶(cast leaf)。用以形成均质化烟草材料片材的工艺通常包括将烟草尘与粘合剂混合以形成浆料的步骤。浆料然后用于产生烟草幅材。举例来说，通过将粘性浆料流延到移动金属带上来产生所谓的流延叶。或者，可使用具有低黏度和高含水量的浆料在类似造纸的工艺中产生再生烟草。The most commonly used forms of homogenized tobacco material are reconstituted tobacco sheet and cast leaf. Processes for forming sheets of homogenized tobacco material typically include the step of mixing tobacco dust with a binder to form a slurry. The slurry is then used to produce a tobacco web. For example, a so-called casting lobe is produced by casting a viscous slurry onto a moving metal belt. Alternatively, reconstituted tobacco can be produced in a paper-like process using a slurry with low viscosity and high water content.
烟草的片材材料可以被称作再生片材材料并且使用颗粒烟草(例如，再生烟草)或烟草颗粒混合物、保湿剂和水性溶剂以形成烟草组合物而形成。可以接着流延、挤出、辊压或按压此烟草组合物以从烟草组合物形成片材材料。烟草的片材可以利用以下工艺形成：湿式工艺，其中碎烟用于制造纸类材料；或流延叶工艺，其中将碎烟与粘合剂材料混合在一起且流延到移动带上以形成片材。Sheet materials of tobacco may be referred to as reconstituted sheet materials and are formed using particulate tobacco (eg, reconstituted tobacco) or a mixture of tobacco particles, a humectant, and an aqueous solvent to form a tobacco composition. This tobacco composition may then be cast, extruded, rolled or pressed to form a sheet material from the tobacco composition. Sheets of tobacco can be formed using either the wet process, where shredded tobacco is used to make paper-like material, or the cast leaf process, where shredded tobacco is mixed with a binder material and cast onto a moving belt to form Sheet.
均质化烟草片材除烟草以外通常优选地包括粘合剂。均质化烟草片材通常优选地包括气溶胶形成剂，诸如瓜尔胶和丙三醇。The homogenized tobacco sheet generally preferably includes a binder in addition to the tobacco. Homogenized tobacco sheets generally preferably include aerosol forming agents such as guar gum and glycerin.
术语“气溶胶形成基材”是指能够释放可形成气溶胶的挥发性化合物的基材。通常，气溶胶形成基材在加热时释放挥发性化合物。气溶胶形成基材可包括含有生物碱的材料，该材料包含挥发性生物碱风味化合物，该挥发性生物碱香料化合物在加热时从气溶胶形成基材释放。气溶胶形成基材可包括均质化材料。The term "aerosol-forming substrate" refers to a substrate capable of releasing an aerosol-forming volatile compound. Typically, aerosol-forming substrates release volatile compounds when heated. The aerosol-forming substrate may comprise an alkaloid-containing material comprising volatile alkaloid flavor compounds that are released from the aerosol-forming substrate upon heating. The aerosol-forming substrate may include a homogenizing material.
为了形成含有生物碱的材料的片材，形成浆料。To form a sheet of alkaloid-containing material, a slurry is formed.
浆料可包括多种不同组分或成分。这些组分可能影响含有生物碱的材料的流延片材的性质。第一成分是含有例如以粉末形式的生物碱的材料。此材料可以是例如烟草粉末掺合物，其优选地含有浆料中存在的大部分烟草。烟草粉末掺合物是均质化烟草材料中大部分烟草的来源，并且因此赋予最终产品风味，例如赋予通过加热均质化烟草材料而产生的气溶胶风味。A slurry may comprise a variety of different components or ingredients. These components may affect the properties of the cast sheet of the alkaloid-containing material. The first component is a material containing the alkaloid, for example in powder form. This material may be, for example, a tobacco powder blend, which preferably contains the majority of the tobacco present in the slurry. The tobacco powder blend is the source of the majority of the tobacco in the homogenized tobacco material, and thus imparts a flavor to the final product, eg, to an aerosol produced by heating the homogenized tobacco material.
优选地，含有生物碱的材料的粉末的大小在约0.03毫米和约0.12毫米之间。对于含有生物碱的材料的颗粒或粉末的大小，意指Dv95大小。上面列出的值中的每个值指示粒度的Dv95。Dv95中的“v”意指考虑了体积分布。体积分布的使用引入了等效球体的概念。等效球体是在我们正在测量的性质上等于真实颗粒的球体。因此，对于光散射方法，它是将产生与真实颗粒相同的散射强度的球体。这基本上是具有相同体积的颗粒的球体。另外，Dv95中的“95”意指其中百分之九十五的分布具有较小粒度并且百分之五的分布具有较大粒度的直径。因此，粒度是根据体积分布的大小，其中95％的颗粒具有小于所述值的直径(具有基本上相同体积的颗粒的对应球体的直径)。60微米的粒度意指95％的颗粒具有小于60微米的直径，其中直径是具有与颗粒对应的体积的球体的直径。Preferably, the size of the powder of the alkaloid-containing material is between about 0.03 mm and about 0.12 mm. By the size of the particles or powder of the alkaloid-containing material, the Dv95 size is meant. Each of the values listed above indicates the granularity of Dv95. "v" in Dv95 means that the volume distribution is considered. The use of volume distributions introduces the concept of an equivalent sphere. Equivalent spheres are spheres that are equal to real particles in the property we are measuring. So, for the light scattering method, it is a sphere that will produce the same scattering intensity as real particles. This is basically a sphere of particles with the same volume. In addition, "95" in Dv95 means a diameter in which ninety-five percent of the distribution has a smaller particle size and five percent of the distribution has a larger particle size. Thus, the particle size is the size according to the volume distribution in which 95% of the particles have a diameter smaller than the stated value (the diameter of a corresponding sphere of particles having substantially the same volume). A particle size of 60 microns means that 95% of the particles have a diameter of less than 60 microns, where diameter is the diameter of a sphere having a volume corresponding to the particle.
使用Horiba LA 950或LA 960粒度分布分析仪测量颗粒的Dv95大小。HORIBA LA-960粒度分析仪使用激光衍射方法来测量粒度分布。该技术使用第一原理，使用从颗粒散射(边缘衍射)并穿过颗粒(二次散射折射)的光来计算大小。LA-960结合了Mie散射理论。The Dv95 size of the particles was measured using a Horiba LA 950 or LA 960 particle size distribution analyzer. HORIBA LA-960 Particle Size Analyzer uses laser diffraction method to measure particle size distribution. The technique uses first principles, using light scattered from a particle (edge diffraction) and passing through the particle (secondary scattering refraction) to calculate size. LA-960 incorporates Mie scattering theory.

More preferably, it is between about 2% and about 4%. The binder used in the slurry may be any of the gums or pectins described herein. The binder can ensure that the powder of the alkaloid-containing material, such as tobacco, remains substantially dispersed throughout the homogenized tobacco web. Although any binder can be used, preferred binders are natural pectins (such as fruit, citrus or tobacco pectin), guar gums (such as hydroxyethyl guar and hydroxypropyl guar), Locust bean gum (such as hydroxyethyl and hydroxypropyl locust bean gum), alginates, starches (such as modified or derivatized starches), cellulose (such as methyl, ethyl, ethylhydroxymethyl and carboxymethyl Cellulose), Tamarind Gum, Dextran, Pullulan, Konjac Flour, Xanthan Gum, etc. A particularly preferred binder for use in the present invention is guar gum.
用于包含在含有生物碱的材料的浆料中的合适的气溶胶形成剂在本领域中是已知的，并且包括但不限于：一元醇(诸如薄荷醇)、多元醇(诸如三甘醇、1,3-丁二醇和甘油)、多元醇的酯(诸如甘油单、二或三乙酸酯)，以及一元、二元或多元羧酸的脂肪酸酯(诸如二甲基十二烷二酸酯和二甲基十四烷二酸酯)。Suitable aerosol-forming agents for inclusion in slurries of alkaloid-containing materials are known in the art and include, but are not limited to: monohydric alcohols (such as menthol), polyhydric alcohols (such as triethylene glycol), , 1,3-butanediol and glycerol), esters of polyols (such as glycerol mono-, di-, or triacetate), and fatty acid esters of mono-, di-, or polycarboxylic acids (such as dimethyldodecane di esters and dimethyltetradecanedioate).
优选的气溶胶形成剂的示例是甘油和丙二醇。Examples of preferred aerosol formers are glycerin and propylene glycol.
浆料可以具有以干重计大于约5％的气溶胶形成剂含量。浆料可以具有以干重计在5％与30％之间的气溶胶形成剂含量。更优选地，气溶胶形成剂占浆料的干重的约10％至约25％之间。更优选地，气溶胶形成剂占浆料的干重的约15％至约25％之间。The slurry may have an aerosol former content of greater than about 5% by dry weight. The slurry may have an aerosol former content of between 5% and 30% by dry weight. More preferably, the aerosol forming agent comprises between about 10% and about 25% by dry weight of the slurry. More preferably, the aerosol forming agent comprises between about 15% and about 25% by dry weight of the slurry.
为了提高作为增强剂的生物碱材料幅材的抗张强度，优选地将含纤维素纤维的纤维素浆液添加到浆料中。In order to increase the tensile strength of the web of alkaloid material as a reinforcing agent, preferably a cellulose slurry containing cellulose fibers is added to the pulp.
在浆料中引入纤维素纤维通常会增加烟草材料幅材的抗张强度，从而用作增强剂。因此，添加纤维素纤维可以增加均质化烟草材料幅材的回弹性。用于包括在用于均质化烟草材料的浆料中的纤维素纤维是所属领域中已知的并且包括但不限于：软木纤维、硬木纤维、黄麻纤维、亚麻纤维、烟草纤维以及其组合。除成浆以外，纤维素纤维可以经受合适的工艺，如精制、机械成浆、化学成浆、漂白、硫酸盐成浆及其组合。纤维素纤维可以包括烟草梗材料、茎或其他烟草植物材料。优选地，纤维素纤维(如木纤维)包含低木质素含量。替代性地，纤维，例如植物纤维，可以与上述纤维一起使用或用于包含竹材的替代物中。纤维素纤维的长度有利地在约0.2毫米和约4毫米之间。优选地，纤维素纤维的根据重量的平均长度介于约1毫米与约3毫米之间。另外，优选地，按干重计，纤维素纤维的量占浆料(或均质化烟草片材)总重量的约1％至约7％。Incorporation of cellulosic fibers in the slurry generally increases the tensile strength of the web of tobacco material, thereby acting as a reinforcing agent. Thus, the addition of cellulosic fibers can increase the resiliency of the homogenized web of tobacco material. Cellulosic fibers for inclusion in slurries for homogenizing tobacco material are known in the art and include, but are not limited to: softwood fibers, hardwood fibers, jute fibers, flax fibers, tobacco fibers, and combinations thereof. In addition to pulping, cellulosic fibers may be subjected to suitable processes such as refining, mechanical pulping, chemical pulping, bleaching, kraft pulping, and combinations thereof. Cellulosic fibers may comprise tobacco stem material, stalks or other tobacco plant material. Preferably, the cellulosic fibers, such as wood fibers, comprise a low lignin content. Alternatively, fibers, such as vegetable fibers, may be used together with the fibers described above or in substitutes comprising bamboo. The length of the cellulose fibers is advantageously between about 0.2 millimeters and about 4 millimeters. Preferably, the average length by weight of the cellulose fibers is between about 1 millimeter and about 3 millimeters. Additionally, preferably, the amount of cellulosic fibers is from about 1% to about 7% by dry weight of the total weight of the pulp (or homogenized tobacco sheet).
纤维的平均长度是指如通过由Techpap SAS商品化的MORFI COMPACT测量的其真实长度(无论它们是卷曲的还是具有扭结)。平均长度是通过MORFI COMPACT在N根纤维的测量上测量的纤维长度的数学平均值，其中N>5。MORFI COMPACT是纤维分析仪，其测量遵循纤维框架的纤维的长度，从而测量它们的实际展开长度。如果测量对象的长度包含在200微米和10000微米之间，并且其宽度包含在5微米和75微米之间，则该测量对象被认为是纤维。当将去离子水添加到纤维中并使用Morfi软件时，测量纤维长度。The average length of the fibers refers to their true length (whether they are crimped or have kinks) as measured by MORFI COMPACT commercialized by Techpap SAS. The mean length is the mathematical mean of the fiber lengths measured by MORFI COMPACT on a measurement of N fibers, where N>5. MORFI COMPACT is a fiber analyzer that measures the length of fibers following the fiber framework and thus their actual developed length. A measuring object is considered a fiber if its length is between 200 microns and 10000 microns inclusive and its width is between 5 microns and 75 microns inclusive. Fiber length was measured when deionized water was added to the fiber and using Morfi software.
优选地，所述浆料在流延时的水分在烟草材料在流延时的总重量的约60％和约80％之间。优选地，浆料中水的量占浆料在流延时的总质量的约60％和80％之间。Preferably, the moisture of the slurry at the time of casting is between about 60% and about 80% of the total weight of the tobacco material at the time of casting. Preferably, the amount of water in the slurry is between about 60% and 80% of the total mass of the slurry when cast.

粘合剂和气溶胶形成剂优选地以约1:30到约1:1的重量比包括在内。更优选地，粘合剂和气溶胶形成剂以约1:20到约1:4的重量比包括在内。The binder and aerosol former are preferably included in a weight ratio of about 1:30 to about 1:1. More preferably, the binder and aerosol former are included in a weight ratio of about 1:20 to about 1:4.
含有生物碱的材料优选地是烟草。粘合剂和烟草粒子优选地以约1:100到约1:10的重量比包括在内。更优选地，粘合剂和烟草粒子以约1:50到约1:15的重量比，甚至更优选地约1:30到1:20的重量比包括在内。The alkaloid-containing material is preferably tobacco. The binder and tobacco particles are preferably included in a weight ratio of about 1:100 to about 1:10. More preferably, the binder and tobacco particles are included in a weight ratio of about 1:50 to about 1:15, even more preferably about 1:30 to 1:20.

More preferably, the aerosol-forming agent and cellulosic fibers are included in a weight ratio of from about 5:1 to about 15:1.

More preferably, the weight ratio of cellulose fibers to tobacco particles is preferably between about 1:50 to about 1:20.
由上述一些或全部成分形成的浆料可例如包含在流延箱中。浆料可以从不同位置到达流延箱。因此，流延箱可能不是浆料形成的地方。例如，浆料可以在筒仓中产生，由筒仓通过合适的管道传送到流延箱。A slurry formed from some or all of the ingredients described above may, for example, be contained in a casting box. Slurry can reach the casting box from different locations. Therefore, the casting box may not be the place where the slurry is formed. For example, the slurry may be produced in a silo, from which it is conveyed by suitable piping to the casting box.
优选地将流延箱内部的浆料保持在大约环境温度，即，在约15摄氏度和约30摄氏度之间。浆料从流延箱流延以形成片材。优选地，将片材流延到可移动支撑件上，例如传送带。The slurry inside the casting box is preferably maintained at about ambient temperature, ie, between about 15 degrees Celsius and about 30 degrees Celsius. The slurry is cast from a casting box to form a sheet. Preferably, the sheet is cast onto a movable support, such as a conveyor belt.
优选地，浆料连续供应到流延箱，同时浆料流延到可移动支撑件上，以形成含有生物碱的材料的连续幅材。因此，筒仓和流延箱优选地流体连接，以便允许浆料从一个流动到另一个。Preferably, the slurry is continuously supplied to the casting box while the slurry is cast onto a movable support to form a continuous web of alkaloid-containing material. Therefore, the silo and casting box are preferably fluidly connected so as to allow slurry flow from one to the other.
这样，优选地在流延箱中保持预定量的浆料。优选地，将浆料连续地供应至流延箱，同时通过流延刮刀将浆料流延至可移动支撑件以形成包含生物碱的材料的连续幅材。然而，其他流延系统，例如辊，也可用于流延含有生物碱的材料的片材。In this way, a predetermined amount of slurry is preferably maintained in the casting box. Preferably, the slurry is continuously supplied to the casting box while the slurry is cast by a casting blade to a movable support to form a continuous web of alkaloid-containing material. However, other casting systems, such as rollers, can also be used to cast sheets of alkaloid-containing material.
流延箱优选地是箱形的。优选地，流延箱包括壁。更优选地，壁又包括侧壁。侧壁可包括第一对相对壁和第二对相对壁，称为第一侧壁、第二侧壁、第三侧壁和第四侧壁。侧壁有利地为基本上竖直的，或相对于竖直平面倾斜。第一侧壁和第二侧壁以及第三侧壁和第四侧壁面对彼此。优选地，流延箱的壁还包括具有孔隙的底壁。优选地，整个底壁限定孔隙。The casting box is preferably box-shaped. Preferably, the casting box comprises walls. More preferably, the wall in turn comprises side walls. The side walls may include a first pair of opposing walls and a second pair of opposing walls, referred to as first, second, third, and fourth side walls. The side walls are advantageously substantially vertical, or inclined relative to a vertical plane. The first and second side walls and the third and fourth side walls face each other. Preferably, the wall of the casting box further includes a bottom wall with pores. Preferably, the entire bottom wall defines the aperture.
移动的支撑件优选地沿着纵向方向移动，以便从流延箱移除浆料。支撑件可包含例如不锈钢可移动带。支撑件优选地由滚筒移动，该滚筒适于推进可移动支撑件。滚筒另外适于与用于流延幅材的可移动支撑物热接触。The moving support preferably moves in the longitudinal direction to remove the slurry from the casting box. The support may comprise, for example, a stainless steel movable belt. The support is preferably moved by rollers adapted to advance the movable support. The rollers are additionally adapted to be in thermal contact with a movable support for casting the web.
在流延后，将流延片材干燥以降低其水分含量。干燥还用于“硬化”片材。为了干燥流延片材，可以使用干燥站，简称为“干燥器”。After casting, the cast sheet is dried to reduce its moisture content. Drying is also used to "harden" the sheet. For drying the cast sheet a drying station, referred to simply as a "dryer" can be used.
在干燥站中，优选地使流延片材的温度升高，使得流延片材内的水分可减少。优选地，所述流延片材在流延时的水分(即，浆料的水分)在浆料总重量的约60％和约80％之间。优选地，所述流延片材在干燥结束时的水分在含有生物碱的材料的片材的总重量的约7％和约15％之间。优选地，含有生物碱的材料的所述片材在干燥结束时的水分在含有生物碱的材料的片材的总重量的约8％和约12％之间。浆料在流延时和干燥过程结束时的水分是控制的重要参数，因为它影响片材的均质性和含有生物碱的材料的片材在后续生产步骤中的可制造性。In the drying station, the temperature of the cast sheet is preferably raised so that the moisture in the cast sheet can be reduced. Preferably, the moisture of the cast sheet (ie, the moisture of the slurry) at the time of casting is between about 60% and about 80% of the total weight of the slurry. Preferably, the moisture of the cast sheet at the end of drying is between about 7% and about 15% of the total weight of the sheet of alkaloid-containing material. Preferably, said sheet of alkaloid-containing material has a moisture at the end of drying of between about 8% and about 12% of the total weight of the sheet of alkaloid-containing material. The moisture content of the slurry at the time of casting and at the end of the drying process is an important parameter to control as it affects the homogeneity of the sheet and the manufacturability of the sheet of alkaloid-containing material in subsequent production steps.
已发现浆料的理想湿度水准在约60％与约80％之间。在此优选范围以下，浆料在流延时的密度使其频繁地造成在流延幅材中出现缺陷。另外，该范围之外的水分水平可能导致流延片材的抗张强度降低，这可能使在后续加工步骤中有效处理含有生物碱的材料的片材复杂化。因此，在干燥步骤期间需要从流延片材移除的多余水分相对较高。The ideal moisture level for the slurry has been found to be between about 60% and about 80%. Below this preferred range, the density of the slurry when cast is such that it frequently causes defects in the cast web. Additionally, moisture levels outside this range may result in reduced tensile strength of the cast sheet, which may complicate effective handling of the sheet of alkaloid-containing material in subsequent processing steps. Therefore, the excess moisture that needs to be removed from the cast sheet during the drying step is relatively high.
水分的移除优选地通过暴露于加热的流体流来进行。例如，加热的流体可以是干燥空气，其中干燥空气的温度高于流延片材的温度。也可以使用蒸汽。Moisture removal is preferably performed by exposure to a heated fluid stream. For example, the heated fluid can be dry air, where the temperature of the dry air is higher than the temperature of the cast sheet. Steam can also be used.
优选地，干燥器沿着干燥管线被分成多个干燥区段。干燥管线被定义为片材在干燥器内沿着其移动的纵向方向。在另一个干燥区段的下游的干燥区段意指沿着片材的移动方向在另一个干燥区段下游的区段。优选地，存在大于一个干燥区段。优选地，独立地控制干燥部分中的每一个，以使得在每一干燥区段中，可与其它部分独立地设定过程参数。优选地，至少第一干燥区段包括第一温度控制装置和第二温度控制装置，该第一温度控制装置和第二温度控制装置继而包括热空气发生器和蒸汽发生器，该热空气发生器和蒸汽发生器适于分别朝向可移动支撑件的第一表面和第二表面喷射热空气和蒸汽。然后将蒸汽引导到支撑件本身，同时将热空气朝向流延到可移动支撑件中的流延片材的自由表面引导。有利地，可以测量和调节喷射流和热空气的流动速率。优选地，过热蒸汽用于减小流延幅材的湿度。Preferably, the dryer is divided into a plurality of drying sections along the drying line. The drying line is defined as the longitudinal direction along which the sheet moves within the dryer. The drying section downstream of the other drying section means a section downstream of the other drying section in the moving direction of the sheet. Preferably there is more than one drying section. Preferably, each of the drying sections is controlled independently so that in each drying section process parameters can be set independently of the other sections. Preferably, at least the first drying section comprises first and second temperature control means which in turn comprise a hot air generator and a steam generator, the hot air generator and the steam generator is adapted to inject hot air and steam towards the first surface and the second surface of the movable support, respectively. The steam is then directed to the support itself, while the hot air is directed towards the free surface of the cast sheet cast into the movable support. Advantageously, the jet and hot air flow rates can be measured and adjusted. Preferably, superheated steam is used to reduce the humidity of the cast web.
加热的流体优选地为热空气、蒸汽或过热蒸汽。加热的流体可以是热空气、蒸汽和过热蒸汽的任何组合。例如，热空气和蒸汽可一起使用。The heated fluid is preferably hot air, steam or superheated steam. The heated fluid can be any combination of hot air, steam and superheated steam. For example, hot air and steam can be used together.
另外，优选地，存在连续的反馈控制，使得从干燥空气发生器喷射的干燥空气和由蒸汽发生器喷射的蒸汽的流动速率或温度或两者可根据干燥区段中的流延片材的温度和水分的值来修改。In addition, preferably, there is continuous feedback control so that the flow rate or temperature of the drying air injected from the drying air generator and the steam injected by the steam generator or both can be adjusted according to the temperature of the cast sheet in the drying section. and moisture value to modify.
干燥器优选地是基本上封闭的环境。加热的流体加热和/或干燥引入干燥器中的流延片材。在该加热和/或干燥过程中，加热的流体不仅可从片材中提取或移除湿度，而且还可提取或移除一些组分，诸如挥发物，例如香料或生物碱。The dryer is preferably a substantially closed environment. The heated fluid heats and/or dries the cast sheet introduced into the dryer. During this heating and/or drying process, the heated fluid can not only extract or remove moisture from the sheet, but also some components, such as volatiles, eg fragrances or alkaloids.
优选地收集或聚集在干燥器内部产生的所得排放物。排放物可以是流体的形式，诸如气体和蒸气、或液体。The resulting effluent generated inside the dryer is preferably collected or collected. Emissions may be in the form of fluids, such as gases and vapors, or liquids.
本发明提出回收干燥器的废热，特别是聚集或收集的排放物中存在的废热。在本发明中可以使用用以从排放物中回收热量的任何已知的方法。The present invention proposes to recover the waste heat of the dryer, in particular the waste heat present in the aggregated or collected effluent. Any known method for recovering heat from exhaust may be used in the present invention.
根据本发明的热量回收可通过回收来自干燥器的排放物的热量来实现，该热量可以从围绕或沿着干燥器的若干位置收集。一些排放物可能来自上部部分，其中“上部部分”指示干燥器在流延片材上方的部分。从上部部分回收的排放物可与来自片材的蒸气和挥发物混合。Heat recovery according to the invention can be achieved by recovering heat from the discharge of the dryer, which can be collected from several locations around or along the dryer. Some emissions may come from the upper section, where "upper section" indicates the part of the dryer above the cast sheet. Emissions recovered from the upper section can mix with vapors and volatiles from the sheet.
来自干燥器的底部部分的一些排放物(其中“下部部分”指示干燥器在流延片材下方的部分)可被聚集并且也可从它们中回收热量。由于蒸气冷凝，从下部部分回收的排放物可能主要是液体。Some discharges from the bottom part of the dryer (where "lower part" indicates the part of the dryer below the cast sheet) can be collected and heat can also be recovered from them. Emissions recovered from the lower section may be predominantly liquid due to vapor condensation.
由于这些排放物的组成不同，因此优选地对每个不同的排放物类型进行单独的热量回收过程。Due to the different composition of these emissions, a separate heat recovery process is preferably performed for each different emission type.
回收的热量可在流延和/或干燥过程中重复使用。优选地，回收的热量在设备内使用以产生含有生物碱的材料的片材。这样，提高了包含生物碱的材料的片材的生产效率。The recovered heat can be reused in the casting and/or drying process. Preferably, the recovered heat is used within the apparatus to produce sheets of alkaloid-containing material. In this way, the production efficiency of sheets of alkaloid-containing material is improved.
另外，该过程不会显著改变干燥器的构造。通常，收集排放物是为了避免在工厂外释放化学/灰尘化合物。因此，本发明的方法不需要高成本地向现有的干燥器添加部件。In addition, the process does not significantly change the construction of the dryer. Typically, emissions are collected to avoid releasing chemical/dust compounds outside the plant. Thus, the method of the present invention does not require costly addition of components to existing dryers.
此外，由于排放物的组成(特别是从干燥器的上部部分收集的那些排放物的组成)可能由于来自逐渐干燥的片材的挥发物的组成的变化而沿着干燥管线改变，因此排放物的收集优选地在沿着干燥管线的不同的区域中进行。Furthermore, since the composition of the effluents, especially those collected from the upper part of the dryer, may change along the drying line due to changes in the composition of the volatiles from the progressively drying sheet, the Collection preferably takes place in different zones along the drying line.
优选地，该方法包括：从干燥期间产生的排放物中回收挥发性物质；以及从回收的挥发性物质中获得香料提取物。在已经收集的排放物中，还存在来自含有生物碱的材料的片材的挥发物。这些挥发物也可被回收并重复使用。Preferably, the method comprises: recovering volatile substances from effluent produced during drying; and obtaining a perfume extract from the recovered volatile substances. Among the effluents that have been collected there are also volatiles from sheets of alkaloid-containing material. These volatiles can also be recovered and reused.
更优选地，从干燥步骤中产生的排放物中回收挥发性物质的步骤包括以下中的一者或多者：More preferably, the step of recovering volatile substances from the effluent produced in the drying step comprises one or more of the following:
-冷凝排放物；- condensate emissions;
-过滤排放物；- filter emissions;
-对排放物进行液-液分离；- Liquid-liquid separation of effluents;
-蒸馏排放物。- Distillation emissions.
特别地，刚好在排放物冷凝之后过滤对于移除排放物内部的可能灰尘可能是有用的。在液-液分离的情况下，然后还优选地进行浓缩步骤。相同浓缩步骤也可在蒸馏步骤之后进行：用于分离排放物的特定化合物的蒸馏步骤。In particular, filtering just after condensation of the effluent may be useful to remove possible dust inside the effluent. In the case of liquid-liquid separation, a concentration step is then preferably also carried out. The same concentration step can also be performed after the distillation step: the distillation step used to separate the specific compounds of the effluent.
更优选地，该方法包括：将香料提取物添加到浆料中。回收的挥发物可再次用于形成含有生物碱的材料的片材。挥发物可用于增强片材的风味或增加片材的一些组分(例如所含生物碱)的浓度。优选地，将所提取的香料重新引入浆料中。More preferably, the method comprises: adding spice extract to the slurry. The recovered volatiles can be reused to form sheets of alkaloid-containing material. The volatiles can be used to enhance the flavor of the sheet or to increase the concentration of some components of the sheet such as contained alkaloids. Preferably, the extracted flavor is reintroduced into the slurry.
优选地，该方法包括在流延之前使用回收的热量来加热浆料。优选地，回收的热量用于流延和/或干燥步骤中，使得生产含有生物碱的材料的片材的整个过程更有效。例如，回收的热量可用于加热浆料，例如包含在流延箱中的浆料。可以通过本领域已知的热量回收机制来回收热量。示例可以是管式热交换器，热泵(对于其热量被回收的材料的温度低于其将被使用的设计区域处的温度的情况)或将排放物从干燥管线的区域驱动到另一个区域的管道。Preferably, the method includes using recovered heat to heat the slurry prior to casting. Preferably, the recovered heat is used in the casting and/or drying steps, making the overall process of producing sheets of alkaloid-containing material more efficient. For example, the recovered heat can be used to heat a slurry, such as that contained in a casting box. Heat can be recovered by heat recovery mechanisms known in the art. Examples could be tube heat exchangers, heat pumps (for the case where the temperature of the material whose heat is being recovered is lower than the temperature at the design area where it will be used) or ones that drive the discharge from one area of the dry line to another pipeline.
通过回收的热量对浆料的这种预热有助于使浆料的液体更多，因为随着温度升高，浆料粘度降低，并且因此有助于浆料的混合和/或流延。This preheating of the slurry by the recovered heat helps to make the slurry more liquid since as the temperature increases the viscosity of the slurry decreases and thus facilitates mixing and/or casting of the slurry.
优选地，该方法包括使用回收的热量在给定位置处加热流延片材。更优选地，该方法包括：使用回收的热量在沿输送方向回收排放物的位置上游的位置对流延片材进行加热。为了帮助干燥器加热流延片材并减少这样做的能量需求，回收的热量可用于在干燥过程期间加热片材。例如，来自干燥器的从给定位置在温度T1下喷射的排放物输出可经由管道(诸如在干燥器内部延伸的导热管)朝向干燥器的排放物在低于T1的温度下喷射的部分引导。离开在较低温度下的位置的排放物可指示干燥器的该位置中的较低内部温度。Preferably, the method includes heating the cast sheet at a given location using recovered heat. More preferably, the method includes heating the cast sheet using the recovered heat at a position upstream of the position where the discharge is recovered in the conveying direction. To help the dryer heat the cast sheet and reduce the energy requirements for doing so, the recovered heat can be used to heat the sheet during the drying process. For example, the output of effluent from a dryer sprayed at a temperature T1 from a given location may be directed via a conduit, such as a heat pipe extending inside the dryer, towards the portion of the dryer where the effluent is sprayed at a temperature lower than T1 . Emissions from a location at a lower temperature may indicate a lower internal temperature in that location of the dryer.
例如，在干燥管线逐渐加热流延片材的情况下，即，流延片材的温度在干燥器内部沿着输送方向移动的同时增加，则区域的排放物输出可在干燥器内部向上游输送，以便帮助加热干燥器的上游区域。在这种情况下，排放物优选地经由合适的管道简单地从干燥器的一个区域转移到另一个区域。For example, in the case where the drying line gradually heats the cast sheet, i.e. the temperature of the cast sheet increases while moving inside the dryer along the conveying direction, the discharge output of the zone can be conveyed upstream inside the dryer , to help heat the upstream area of the dryer. In this case, the discharge is preferably simply diverted from one area of the dryer to the other via suitable piping.
干燥器的底部部分区域的排放物输出可用于加热干燥器的上部部分区域。在底部部分中，通常加热的流体是蒸汽，并且在干燥管线中使用的蒸汽通常比在干燥器地上部部分中使用的热的干燥空气更热。收集的蒸汽作为排放物可用于帮助加热其他底部部分区域，然后可被引导到干燥器的上部部分中，以帮助加热上部部分区域。The discharge output from the bottom section of the dryer can be used to heat the upper section of the dryer. In the bottom section, usually the heated fluid is steam, and the steam used in the drying line is usually hotter than the hot drying air used in the upper part of the dryer. The steam collected as a discharge can be used to help heat the other bottom section areas and can then be directed into the upper section of the dryer to help heat the upper section areas.
优选地，该方法包括：在干燥期间沿着输送方向输送流延片材；以及收集在干燥步骤中从沿着输送方向的不同位置产生的排放物。更优选地，该方法还包括根据排放物的收集位置从排放物中获得不同的物质。Preferably, the method includes: conveying the cast sheet along a conveying direction during drying; and collecting discharges generated during the drying step from different positions along the conveying direction. More preferably, the method further comprises obtaining different substances from the effluent depending on where the effluent is collected.
沿着干燥器管线的单独收集点可用于收集含有不同挥发物的排放物的不同级分。不同的挥发物可具有不同的香味性质。实际上，流延片材的组成可随着干燥过程变化，因此，沿着输送方向，排放物可能不包含相同的挥发物。如所指出的，在这样的回收期间可以使用不同的处理(例如，冷凝、过滤、液-液分离、蒸馏等)，并且这些处理和/或此类处理的输出可根据干燥管线的回收排放物及其挥发物的区域来分离。Separate collection points along the dryer line can be used to collect different fractions of the effluent containing different volatiles. Different volatiles can have different fragrance properties. In fact, the composition of the cast sheet may vary with the drying process, therefore, the discharge may not contain the same volatiles along the conveying direction. As noted, different processes (e.g., condensation, filtration, liquid-liquid separation, distillation, etc.) can be used during such recovery, and the output of these processes and/or such processes can be based on the recovery effluent of the dry line and its volatile region to separate.
优选地，该方法包括：将浆料流延到可移动支撑件上；以及从可移动支撑件中回收热量。Preferably, the method comprises: casting the slurry onto a movable support; and recovering heat from the movable support.
有利地，可移动支撑物包括环状不锈钢输送带。不锈钢为允许容易的热传递的材料，因为其为良好导热体。同时，不锈钢带降低了流延片材牢固地附接到支撑件的风险，因此可允许在干燥步骤之后从可移动支撑件完全和连续地移除流延片材。在流延片材的生产过程期间，在流延片材已经至少部分干燥之后，将流延片材从可移动支撑件移除，以便进行进一步处理。然后优选地将流延片材进一步干燥、冷却、然后卷绕成卷筒。环状可移动支撑件返回到流延箱的位置，使得可以将另外的浆料流延到可移动支撑件上。流延片材从支撑件的移除优选地通过称为刮浆刀的刮刀来进行。在流延片材牢固地“胶粘”到支撑件上的情况下，刮浆刀的作用可能会导致流延幅材的破裂和机器中断。因此，优选的是尽可能容易地从支撑件移除流延片材。已经发现使用不锈钢作为用于支撑件的材料是优选的解决方案。另外，不锈钢可被加工成片材的流延所需的高精度。这使得不锈钢是作为可移动支撑物的有成本效益的材料。Advantageously, the movable support comprises an endless stainless steel conveyor belt. Stainless steel is a material that allows easy heat transfer because it is a good heat conductor. At the same time, the stainless steel belt reduces the risk of the cast sheet being firmly attached to the support, thus allowing complete and continuous removal of the cast sheet from the movable support after the drying step. During the production process of the cast sheet, after the cast sheet has been at least partially dried, the cast sheet is removed from the movable support for further processing. The cast sheet is then preferably further dried, cooled and then wound into a roll. The annular movable support returns to the position of the casting box so that additional slurry can be cast onto the movable support. Removal of the cast sheet from the support is preferably performed by a doctor blade known as a doctor blade. In cases where the cast sheet is firmly "glued" to the support, the action of the doctor blade may cause breakage of the cast web and machine interruption. Therefore, it is preferable to remove the casting sheet from the support as easily as possible. The use of stainless steel as material for the supports has been found to be the preferred solution. In addition, stainless steel can be processed to the high precision required for casting of sheets. This makes stainless steel a cost-effective material for movable supports.
由于可移动支撑件与流延片材接触的事实，在干燥器中加热流延片材意味着还加热可移动支撑件。优选的是还回收并重复使用该热量，否则该热量将被浪费。优选地，在干燥步骤之后，即在干燥器外部，回收来自可移动支撑件的热量。例如，一些冷却水可被送到可移动支撑件附近，并且由支撑件加热的水可以被重复使用以加热流延设备和/或干燥器的部分。该热量回收系统可联接到已经存在于一些生产线上的现有冷却水管路以冷却可移动支撑件。Due to the fact that the movable support is in contact with the cast sheet, heating the cast sheet in the dryer means also heating the movable support. It is preferred to also recover and reuse this heat, which would otherwise be wasted. Preferably, after the drying step, ie outside the dryer, heat is recovered from the movable support. For example, some cooling water can be sent near the movable support, and the water heated by the support can be reused to heat parts of the casting equipment and/or dryer. This heat recovery system can be coupled to existing cooling water lines already present on some production lines to cool the movable supports.
这种由可移动支撑件加热的水可通过将其送至热交换器来重复使用。This water heated by the movable support can be reused by sending it to a heat exchanger.
在第一实施方案中，在清洁可移动支撑件的同时进行热量回收。在可移动支撑件离开干燥器之后，优选地使用水对其进行清洁。例如，可将水喷洒在可移动支撑件的不与片材接触的表面上。这种用于清洁可移动支撑件的水通常具有“冷”温度，例如约12摄氏度，并且由于与可移动支撑件的接触而被加热到高于20摄氏度的温度。In a first embodiment, heat recovery is performed while cleaning the movable support. After the movable support leaves the dryer, it is preferably cleaned with water. For example, water may be sprayed on the surface of the movable support that is not in contact with the sheet. Such water used for cleaning the movable support typically has a "cold" temperature, eg about 12 degrees Celsius, and is heated to a temperature above 20 degrees Celsius due to contact with the movable support.
水对可移动支撑件的冷却还可以带来另一个优点。首先，冷却水加热，然后重复使用。另外，冷却水可能有助于在可移动支撑件返回到流延阶段时使其温度均匀。期望的是，在流延时，可移动支撑件具有均匀的温度，因为不均匀的温度可在干燥期间导致片材的不均匀性，从而改变产品一致性并产生缺陷。The cooling of the movable support by water can also bring another advantage. First, the cooling water is heated and then reused. Alternatively, cooling water may help to even out the temperature of the movable support as it returns to the casting stage. It is desirable that the movable support have a uniform temperature when casting, as non-uniform temperatures can cause non-uniformity in the sheet during drying, changing product consistency and creating defects.
根据优选的实施方案，可移动支撑件的温度通过水冷却分配器来调节。优选地，水用于冷却可移动支撑件，例如冷却使其移动的滚筒，因为支撑件的温度通常高于流延时的期望温度，这是由于支撑件从干燥区段返回的事实，其中支撑件和流延幅材被加热以从流延幅材移除水分。由于水的可供使用性和高热容量，水为将目标(在此状况下为滚筒)的温度维持受控于某一范围内的良好和有成本效益的方法。According to a preferred embodiment, the temperature of the movable support is regulated by means of a water cooling distributor. Preferably, the water is used to cool the movable support, such as the drum that moves it, because the temperature of the support is usually higher than expected when casting, due to the fact that the support returns from the drying section, where the support The piece and the cast web are heated to remove moisture from the cast web. Due to its availability and high heat capacity, water is a good and cost-effective way to maintain the temperature of the target (in this case the drum) within a controlled range.
也可以在将片材卷绕成卷筒之前进行用水冷却，然后将水加热，然后重复使用。这种冷却还可以通过冷空气(而不仅是水)来进行。然后，被加热的空气例如经过热交换器，然后被重复使用。这样的热量回收也将具有若干益处，因为在卷绕片材之前的冷却降低了由片材形成的层一旦在卷筒中就彼此粘附的趋势。层的这种“粘性”是当前的问题，因为它可能会导致下游机器的减速，或甚至堵塞。It is also possible to cool the sheet with water before winding it into a roll, then heat the water and reuse it. This cooling can also be done by cold air (not just water). The heated air then passes, for example, through a heat exchanger and is then reused. Such heat recovery will also have several benefits, as the cooling prior to winding the sheet reduces the tendency of the layers formed from the sheet to stick to each other once in the roll. This "stickiness" of the layers is a current problem, as it may lead to slowing of downstream machinery, or even blockage.
优选地，该方法包括：收集在干燥步骤期间形成的水，以及从收集的水中回收热量。优选地，在干燥器中，通过蒸汽发生器从下方加热流延片材。蒸汽会在干燥器的下部部分冷凝并形成水。这种加热的水可被收集并且其中存在的热量可被回收，例如将其输送到流延和/或干燥设备的其他位置。Preferably, the method comprises collecting water formed during the drying step, and recovering heat from the collected water. Preferably, in the dryer, the cast sheet is heated from below by means of a steam generator. The steam condenses and forms water in the lower part of the dryer. This heated water can be collected and the heat present therein can be recovered, eg conveyed to other locations in the casting and/or drying apparatus.
优选地，该方法包括：使用回收的热量来分离回收的挥发性物质。为了从排放物中获得挥发性物质，从相同的排放物中回收的热量可用于例如蒸馏过程。该实施方案显示出废热回收与废挥发物回收之间的强耦合。Preferably, the method comprises: using recovered heat to separate recovered volatile species. To obtain volatile substances from the effluent, the heat recovered from the same effluent can be used, for example, in a distillation process. This embodiment shows a strong coupling between waste heat recovery and waste volatiles recovery.
优选地，从在干燥步骤中产生的排放物中回收热量的步骤包括以下中的一者或多者：通过热交换器回收热量；通过热泵回收热量；或通过管道输送排放物。排放物中存在的热量可用于例如加热水。加热的水然后可在管道中流动并加热设备的其他部分，以用于生产含有生物碱的材料的片材。替代地，排放物可流过热交换器，从而加热其中的流体。排放物可以是液体或气体的形式。Preferably, the step of recovering heat from the effluent produced in the drying step comprises one or more of: recovering heat through a heat exchanger; recovering heat through a heat pump; or conveying the effluent through piping. The heat present in the discharge can be used, for example, to heat water.
